Perhaps I did not explain well, the problem I'm having is with the channels, nor with the movements of the stick are all right but with the ailerons, simply put the aileron stick is not centered on the control unit, but it is recognized as same center to -118% and even if I move on the radio all the stick in the opposite side down to 0% and not more than, unfortunately, this problem causes me lowering aileron servo and the pitch servo gets up, I checked everything on radio and is also centered around I used a model that is used on a non pro-functioning unit, and I have the same problem does not ailerons are seen, but at 0% or +118 or -118.
What should I do to fix it? What checks? I put the picture for you to understand the problem.
The controller has been buying two months ago or maybe one is has never been used until now so I do not know if it can be a problem of any such or other. I expect a confident your help in solving as soon as possible in order to fly
The photos I think pretty well explain the problem, unfortunately the servants with this setting can not move as they should and so for now I can not set the helicopter.
